            Bug ID: 781204
           Summary: kms create a buffer with the strides mismatch input
                    buffers(non-DMA, like rawvideoparse)
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad

          Reporter: ayaka at soulik.info
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

kmssink would work with with the DMABUF since it would just use the strides and
offsets from the meta data of the input buffer.
But with a upstream element like rawvideoparse which is non DMABUF there is a
problem.
This problem could be solved easily, but the strides of the image buffer have
been alignment with a base, the strides calculate from the video information
may not be enough.
